Corcel Exploration Inc. (CSE: CRCL,OTC:CRLEF) (OTCQB: CRLEF) (the ‘Company’ or ‘Corcel’) today announced it has successfully posted and received official acceptance of the required reclamation bond from the US Bureau of Land Management (‘BLM’) for its Yuma King project (the ‘Project’) in Arizona.

With the bond now formally approved and selected the company is now authorized to begin site preparations and drilling at the project. Corcel is planning to drill approximately 1,500 metres of diamond core across 6-8 drill sites, targeting copper and gold skarn and porphyry-style mineralization. The program will focus on targets in and around the Yuma King Mine identified through recent drone magnetic geophysical surveys and geochemical sampling. Highlights from the historical drilling at the Yuma King Mine include intersections of 0.78% Cu, 0.53 g/t Au, and 6.3g/t Ag over 45.4m in Cu-Au skarn.

The objectives of the 2026 drill program are to:

• Confirm historical drill results
• Expand Cu-Au mineralization along strike and down dip at the Yuma King Mine
• Identify new zones of high-grade Cu-Au mineralization

Initial drilling at the Yuma King Mine zone is designed to test both skarn/replacement and porphyry mineralization styles, as the system remains open in multiple directions and at depth.

Corcel has also commenced a ground induced polarization (IP) geophysical survey at the Project. The 10-line km 2D pole-dipole IP geophysical survey that will cover the Yuma King West and Yuma King mine priority exploration targets.

The IP survey is designed to transect target areas where alteration and mineralization are exposed through windows in thin structural cover. The high-resolution survey will help in defining the geological and structural framework as well as detecting sulphide mineralization. The IP survey will be combined with the preciously conducted drone magnetics and surface geochemistry data to enhance the geological model and to fine-tune drill targets for a follow up drill program.

‘Receiving official acceptance of our reclamation bond from the U.S. Bureau of Land Management is an important milestone for Corcel, as it allows us to move forward with site preparation and drilling at Yuma King.’ Commented CEO Jon Ward. ‘With permits now in place, we are preparing to begin our 1,500-metre drill program across multiple priority targets at the project. At the same time, we have commenced an induced polarization survey to help us better understand the potential scale and strength of mineralization across the property. Combined with our existing exploration data, this work will guide our drilling and position us to efficiently advance the Yuma King Project.’

Gold Runner Exploration Inc. (CSE: GRUN) (FSE: CE70) (‘Gold Runner’ or the ‘Company’) is pleased to announce that the Canadian Securities Exchange has approved Gold Runner’s Option Agreement, dated January 21, 2026 as amended January 26, 2026, with the B-ALL Syndicate Ltd. (‘B-All’ or the ‘Optionor’) to acquire a 100% interest in the Golden Girl Property (‘Golden Girl Property’, ‘Golden Girl’ or ‘Property), from the B-ALL Syndicate, the same team that generated and staked Goliath Resources (TSXV: GOT) Surebet Discovery and contributed to advancing that discovery to where it is today. The B-ALL Syndicate also generated and staked the Big One discovery that was subsequently optioned to Juggernaut Exploration (TSXV: JUGR,OTC:JUGRF) and is situated adjacent to Galore Creek. Golden Girl is located approximately mid-way between Goliath’s Surebet Discovery and Juggernaut’s Big One discovery.

As described in the Company’s news release dated January 23, 2026, the Golden Girl property covers an area of 8,471 hectares (ha) in the Iskut River region of Northwestern British Columbia, just 17 kilometers from the Snip Mine and 14 kilometers from the Bronson Airstrip. Exploration conducted by B-ALL on the Golden Girl property identified a large new gold-silver system measuring 12 km by 7 km. The system features a gold-rich core surrounded by a silver-rich halo. Highlights from the 2024 exploration program include grab samples assaying up to 11.28 g/t Au, 3,262 g/t Ag, 5.37% Cu, 20% Pb, and 14.15% Zn, and channel cuts assaying up to 3.74 g/t Au, 2105.45 g/t Ag, 0.88% Cu, 5.48% Pb, and 7.42% Zn.

The nearby, past-producing Snip Gold Mine, historically produced approximately 1 million ounces of gold, 390,000 ounces of silver, and 249,276 kilograms of copper (at an average 127.5 grams per ton gold over 8 years). Eskay Creek, which lies approximately 60 km east of Golden Girl, produced approximately 3.3 million ounces of gold and 160,000 ounces of silver between 1994 and 2008 (with an estimated 3.3 million ounces of gold, 88 million ounces of silver in reserves). It should be noted that Eskay Creek Mine has recently been permitted to re-commence mining operations – see Skeena Resources Ltd. news releases dated January 28, 2026, and February 3, 2026. The reader is reminded that the information provided herein from neighbouring projects and properties is not necessarily indicative of resources and should not be relied upon for the determination of mineralization or potential results of the Company’s properties.

High-grade mineralization at Golden Girl occurs in structurally controlled shear zones within sulphide-rich veins, stockwork, and breccias, similar to the nearby Snip Gold Mine. Hydrothermal fluids took advantage of pre-existing structures to deposit gold-silver-rich mineralization as well as sulphides such as chalcopyrite, galena, and sphalerite associated with quartz-carbonate-rich veins. Pervasive alteration associated with fluid infiltration is often observed surrounding the zones of strong gold-silver mineralization assaying up to 11.28 g/t Au, 3,262 g/t Ag, 5.37% Cu, 20% Pb, and 14.15% Zn and channel cuts assaying up to 3.74 g/t Au, 2105.45 g/t Ag, 0.88% Cu, 5.48% Pb and 7.42% Zn.

More than 95% of the Golden Girl property remains unexplored. Rapid glacial retreat and snowpack abatement over the last 35 years have revealed vast areas of new outcrop that have never seen historical surface exploration. Gold Runner has begun planning and scheduling of prospecting, sampling, and mapping, as well as detailed geophysical surveys over the property during the current exploration season in preparation for the inaugural drill program.

Pursuant to the terms of the Option Agreement, the Company has paid the initial option fee of $250,000. And the Company has also issued to the members of the B-ALL Syndicate, an aggregate of 1,830,000 common shares at a price of $1.13 per common share plus 1,830,000 common share purchase warrants exercisable within 5 years from the date of issuance at an exercise price of $1.14 per common share. The securities issued hereunder are subject to the requisite four-month and one-day hold period from the date of issuance. The parties to the Option Agreement are arm’s length.

Chris Wensley, CEO of Gold Runner, states, ‘We are now fully funded to undertake and complete the 2026 exploration program on Golden Girl. Preparations are already underway to begin expanding on the excellent work done by the B-ALL Syndicate team, who generated Golden Girl. We are on schedule to commence this vital and much-anticipated field work by July 2026 and define our maiden drill program for the following season. This is a tremendously exciting time for the Company and our team. We look forward to executing and delivering on our plan and bringing notable results to our shareholders.’

Stallion Uranium Corp. (the ‘Company’ or ‘Stallion’) (TSX-V: STUD; OTCQB: STLNF; FSE: FE0) is pleased to announce the completion of an extension to its previous ground gravity survey along the Coyote Corridor, located within the Southwestern Athabasca Basin Joint Venture (‘JV’) Project in partnership with Atha Energy Corp. (TSX-V: SASK).

The recently completed program represents a direct extension of the Company’s original gravity grid and was designed to expand coverage over gravity responses observed along the margins of the initial survey area. The objective of the extension was to determine whether these edge anomalies form part of a larger, continuous gravity feature associated with the interpreted structural corridor at Coyote.

Data from the expanded survey is currently undergoing processing, quality control, and preliminary modelling. The Company will provide results once interpretation has been completed.

Highlights:

• Significant gravity low anomaly identified, closely resembling the geophysical signatures of NexGen Energy’s Arrow Deposit and other significant discoveries in the Athabasca Basin
• Structural and geophysical features align with those of the Arrow Deposit and PCE discovery, reinforcing the potential for Tier-1 uranium mineralization
• Gravity anomaly located in a structurally complex corridor, characterized by intersecting conductors and breaks, which are prime settings for uranium deposition
• Ongoing 3D Inversion of Ground Gravity to identify depth and shape of the gravity anomaly

‘The completion of this gravity extension is an important step in systematically advancing the Coyote Target,’ said Matthew Schwab, CEO of Stallion Uranium. ‘Expanding the grid ensures we fully evaluate gravity responses identified at the edges of the initial survey and maintain a disciplined, data-driven approach to exploration.’

Darren Slugoski, Vice President Exploration, added,

‘This extension allows us to properly assess the continuity of gravity features along the structural corridor before finalizing drill targeting. With data processing underway and a potential eastern grid about to commence, we continue to build a comprehensive geophysical dataset across the broader Coyote trend.’

Figure 1: Ground Gravity Survey Location showing Extension of Corridor to the SW

Survey Extension Overview:

The gravity survey extension increases overall coverage across the Coyote structural corridor and enhances density control along strike and across interpreted conductive breaks. The combined original and extended grid now provides improved resolution of subsurface density variations that may be associated with alteration and basement structural complexity.

Gravity surveys are a key component of Stallion’s integrated exploration approach, as gravity lows within the Athabasca Basin are commonly associated with hydrothermal alteration systems developed along graphitic basement structures.

The survey encompassed a total area of 2,097 hectares, with 2,226 gravity stations strategically placed to detect subsurface variations in density that may indicate uranium alteration. The results revealed a substantial gravity low anomaly, a hallmark feature associated with large-scale uranium deposits, such as NexGen Energy’s Arrow Deposit. The Arrow Deposit, one of the most significant uranium discoveries in the Athabasca Basin, shares multiple geological and geophysical similarities with the Coyote Target, strengthening confidence in the potential for a high-grade uranium discovery.

About the Ground Gravity Survey:

Concluding February 10, 2026, MWH Geo-Surveys (Canada) Ltd. carried out a gravity survey at the Coyote Target in Saskatchewan. The survey utilized a customized L&R digital, electronic feedback gravity meter, operated via proprietary controller software. These advanced gravity meters, incorporating electronic levels and electronic nulling, ensure fast, accurate, and reliable readings, particularly in cold-weather conditions.

At each gravity station, GControl software, developed by MWH Geo-Surveys, recorded gravity samples at 1-second intervals. The resultant average of these readings was used as the final gravity measurement, significantly reducing high-frequency noise caused by wind and ground motion. Additionally, GControl calculated real-time, location-specific tidal corrections during data collection, enhancing the accuracy and reliability of the survey results.

With a typical mean data accuracy of 0.02 mgals, MWH Geo-Surveys continues to set the standard for high-resolution gravity surveys, delivering reliable results for resource exploration and geophysical studies.

Lahontan Gold Corp. (TSXV:LG,OTC:LGCXF, OTCQB:LGCXF, FSE:Y2F)  (the ‘Company’ or ‘Lahontan’) is pleased to announce the final analytical results from our 2025 maiden drilling program at the Company’s satellite West Santa Fe project, located only 13 km from Lahontan’s flagship asset, the Santa Fe Mine project, in Nevada’s prolific Walker Lane. The assay results are from the final reverse-circulation rotary (‘RC’) drill are summarized below:

• WSF25-04R: 36.6 metres (0.0 – 36.6m) grading 3.11 g/t Au Eq including 10.7 metres (1.5 – 12.2m) grading 5.75 g/t Au Eq from the surface, all oxide.  The drill hole emphasizes the high gold and silver grades associated with the South Zone at West Santa Fe.
  • Also included in the intercept is a second high grade zone: 12.2m (22.9 – 35.1m) grading 3.67 g/t Au Eq.
  • Individual intercepts range up to 12.04 g/t Au Eq (1.52m, 27.43 – 28.96m, 4.48 g/t Au, 648 g/t Ag).
  • The grade and geometry of these intercepts correlate well with adjacent historic drill holes, further validating the historic drill hole database (please see cross section below).

Notes: Au Eq equals Au (g/t) + ((Ag g/t/60)*0.70). Silver grade for calculating Au Eq is adjusted to consider estimated metallurgical recovery reported by Kappes Cassiday (1982). True thickness of the intercepts is estimated to be 75-90% of the drilled interval. Numbers may not total precisely due to rounding.

Historic drilling, coupled with the 2025 Lahontan RC drilling, defines a gold and silver mineralized zone with a surface expression of 500 by 350 metres with a true thickness from 35 to over 60 metres. With oxide mineralization starting at the surface, there is good potential to exploit this system utilizing low-cost open pit mining and heap-leach processing.

Kimberly Ann, Lahontan Executive Chair, President, CEO, and Founder commented: ‘The robust assay results from WSF25-04R confirm the high-grade core of the South Zone as defined by historic drilling and underground mine workings. We are continuing to model the West Santa Fe system to better understand the geology and geometry of gold and silver mineralization. The geologic team is also fine-tuning a follow-up RC drilling campaign to commence in Spring. Previous field work, including geologic mapping, rock-chip sampling, and airborne magnetic surveys, confirms that the hydrothermal system at West Santa Fe extends at least 1,000 metres east of the main zone of gold and silver mineralization defined by Lahontan and historic drilling (please Lahontan Gold press release dated June 18, 2024). This possible extension of the main mineralized zone, plus untested down-dip extensions of gold and silver mineralization, will be the key targets of the Spring drilling campaign. West Santa Fe continues to be an exciting new exploration target for the Company, one with excellent potential to add important shallow, oxide gold and silver resource ounces to Lahontan’s mineral resource ledger.’

Cross section through drill hole WSF25-04R, West Santa Fe project, Nevada. The results from this drill hole are very similar to historic drilling, in both the grade of gold mineralization and the geometry of the system. Mineralization remains open down-dip to the north-northwest. Note the outcropping nature of the oxidized gold and silver mineralization.

Photo of RC drill cutting from drill hole WSF25-04R, West Santa Fe project, Nevada. The high-grade gold and silver mineralized zones are characterized by thoroughly oxidized limestone. Silicification accompanied by quartz veining is seen in the highest-grade areas (see inset photo above).

Gold and silver mineralization at West Santa Fe is hosted by Triassic age limestone of the Pamlico Formation. The balance of this rock unit is siliceous volcanic and volcaniclastic rock, a strong chemical contrast to the highly reactive carbonate rock, thus mineralization is strongly controlled by stratigraphy. On a detailed scale, higher gold and silver grades are associated with abundant goethite, hematite, and silver halides such as cerargyrite and embolite. While silicification and quartz veining are important hydrothermal alteration features, abundant calcite veining usually accompanies the mineralized intervals.

Brian J. Maher, Lahontan Vice President – Exploration and Founder commented: ‘The maiden RC drilling campaign at West Santa Fe has been very successful. The geologic setting and mineralogy observed in outcrop and drill holes help explain the good gold and silver recoveries reported previously (Kappes Cassiday, 1982): Thoroughly oxidized horizons accompanied by silver halides. The next phase of exploration at West Santa Fe will focus on testing the eastern extension of the main mineralized zone and exploring down-dip from the main mineralized zone where folding may duplicate the hydrothermal system to the north. Exciting early success with opportunities to significantly expand the size and volume of the gold and silver mineralized system.’

QA/QC Protocols

Lahontan conducts an industry standard QA/QC program for its core and RC drilling programs. The QA/QC program consisted of the insertion of coarse blanks and Certified Reference Materials (CRM) into the sample stream at random intervals. The targeted rate of insertion was one QA/QC sample for every 16 to 20 samples. Coarse blanks were inserted at a rate of one coarse blank for every 65 samples or approximately 1.5% of the total samples. CRM’s were inserted at a rate of one CRM for every 20 samples or approximately 5% of the total samples.

The standards utilized include three gold CRM’s and one blank CRM that were purchased from MEG, LLC of Lamoille, Nevada (formerly Shea Clark Smith Laboratories of Reno, Nevada). Expected gold values are 0.188 g/t, 1.107 g/t, 10.188 g/t, and -0.005 g/t, respectively. CRM’s with similar grades are inserted as the initial CRM’s run out. The coarse blank material comprised of commercially available landscape gravel with an expected gold value of -0.005 g/t.

As part of the RC drilling QA/QC process, duplicate samples were collected of every 20^th sample interval at the drill rig to evaluate sampling methodology. Samples were collected from the reject splitter on the drill rig cyclone splitter. Samples were collected at each 95- to 100-foot (28.96 – 30.48m) mark and labeled with a ‘D’ suffix on the sample bag. No duplicates were submitted for core.

All drill samples were sent to American Assay Laboratories (AAL) in Sparks, Nevada, USA for analyses. Delivery to the lab was either by a Lahontan Gold employee or by an AAL driver. Analyses for all RC and core samples consisted of Au analysis using 30-gram fire assay with ICP finish, along with a 36-element geochemistry analysis performed on each sample utilizing two acid digestion ICP-AES method. Tellurium or 50-element analyses were performed on select drill holes utilizing ICP-MS method. Cyanide leach analyses, using a tumble time of 2 hours and analyzed with ICP-AES method, were performed on select drill holes for Au and Ag recovery. AAL inserts their own blanks, standards and conducts duplicate analyses to ensure proper sample preparation and equipment calibration. We have all results reported in grams per tonne (g/t).
